Titertek-Berthold - Crocodile Mini Workstation for ELISA (Five in one: dispenser, washer, incubator, shaker and reader)

Your personal ELISA automation. Crocodile is a compact, fully automated, high performance ELISA workstation for low to medium throughput.

Under normal circumstances, running your ELISA assays required an hour and more of your attention. It was hard to plan other important activities while your assay was in process. Crocodile provides the same functionality as five individual instruments in a footprint similar to a standard stand-alone-reader. The use of Crocodile will reduce assay times by eliminating the need to move plates between dispenser, washer, incubator, shaker and reader. This allows you to perform other important activities and be even more productive.

 

A compact workstation that fits anywhere

Crocodile is only 26.5 cm wide. With all reagent bottles placed to the left of the instrument, it requires no more than 40 cm of bench space – the width of a typical ELISA reader.

 

Walk away automation

The workstation is designed for truly unattended operation. Simply insert the sample microplate which includes standards and samples, choose the assay protocol and leave the work to Crocodile.

 

Easy hardware setup

All functional modules are housed in one compact box. Connect the unit with the power outlet and a notebook or desktop computer. The tubing for wash and waste liquids is preinstalled, ready to be introduced into the wash and waste bottles.

 

Fast start

In everyday use, preparing to use Crocodile won't give you any headaches. Wash, waste, and reagent bottles are readily accessible, right next to the instrument. The instrument requires minimal startup time.

 

Easy maintenance and reliable service

After every use, simply flush the tubing system. You will find that, as with all liquid handling instruments, the tubing system must be replaced from time to time. Accessing the required components and parts is very easy. Trained technical staff is available to help if needed, and after-warranty service agreements are available in most geographical locations – to ensure troublefree operation over the lifetime of the instrument.

 

An open system

Crocodile will adapt to any ELISA format; including sandwich, competitive, or other. Reagent bottles of any shape and size are accommodated by the carefully designed and tested bottle holders.

 

Validation made easy

Many labs regularly validate the performance of the instruments which generate measurement data. For Crocodile, this task is supported by our 3Q Package: Installation Qualification, Operation Qualification and Performance Qualification steps are performed according to detailed instructions provided. The results are documented in checklists according to the specific features of the instrument.

 

Regulatory compliance

Crocodile has been developed according to the most stringent regulations in the industry: DIN ISO 13485. Every step was accompanied by thorough risk analysis. Selection of raw materials and the assembly process is performed under strict observation of released procedures and processes. After final assembly, every individual unit has undergone several days of extensive testing and will be accompanied by a certificate of analysis stating compliance with specifications.

 

PC-Software

The user friendly software adapts to any ELISA protocol easily. The five different functions can be aligned in any sequence, one or several times each (for example one to four dispensing steps or multiple washing steps). Setting of each step is flexible and intuitive. Once you have chosen an assay protocol, the screen will show a graphic of the entire assay schedule, as it will be performed by Crocodile.
